JAMES J'. LAWLER, OF PELHAIII, NEW YORK.

"URINAL.

To all whom it may concern Be it known that T, JAMns J. LAWLER, a citizen of the United States, and resident of Pelham, in the county of V estchester and State of New York, have invented certain new and useful Improvements in Urinals, of which the following is a specification.

This invention relates to urinals, and has for its object the production of a urinal which is automatically flushed by the change in temperature of the water passing into and through the urinal.

T will premise my description by stating that urinals in public places, flushed automatically by timed devices waste considerable water for the reason that the urinals are flushed whether they have been used or not. Devices operated by hand are almost constantly ignored by users, as observations clearly prove. To overcome these objections, T have produced a urinal which is automatic under all conditions, as will be seen in the operation hereinafter described.

Reference being had to the accompanied drawings, Figure 1 is a side view, partly in section of a modern urinal, extending to the floor, to which my automatic flushing device is attached. Fig. 2 is a wall supported urinal, showing method of attaching, the mechanism above the urinal (not shown) being similar to that shown in Fig. 1. Fig. 3 is a front elevation,enlarged, of the automatic flushing device, showing method of connecting up. Fig. 4 is a side elevation of Fig. 3. Fig. 5 is a side central sectional View of Fig. 4, and Fig. 6 is a front central sectional View of Fig. 3, the diaphragm chamber being partly broken away in elevation.

Similar reference characters denote like parts in the several views.

The urinal 1 is of usual construction and preferably of porcelain or enameled iron. In a recess in the base, 1, an annular hollow ring, 2, of thin metal is placed; above this ring is a strainer, 3. A pipe, 4, of small caliber, is connected to the ring, 2, and extends upwardly to the inner side of the diaphragm chamber, 5. A diaphragm 6, of suitable metal is held in position by the front plate, 5, of the diaphragm chamber.- A suit- Specification of Letters Patent.

able washer, 7, with screw ,7 is placed centrally on the diaphragm, connecting with and passing through another washer, 8, a plate 9, and a bushing, 10, the screw 7 projecing a short distance beyond the face of the plate, 5 which is provided with an opening, 5*, as shown. Below this opening two studs 5 project, between which an L crank, 11, is pivotally mounted, a pin 12 acting as a journal. On the free end of this crank an adjusting screw 13 is provided. A series of arms 5 are cast integral with the inner part of the diaphragm chamber, for fastening to a wall., The two plates forming the case for the diaphragm are secured together by screws, 5, which also pass through the diaphragm and make an air and watertight joint. On the front plate, 5, an arm 5 projects outward and another arm, 5 somewhat wider, extends down and outward for supporting the body of a Valve case, 14, which is also provided with arms 14, 14 for attachment by screws or otherwise. This valve is comprised of a'case, 14, having a central longitudinal opening. A valve seat 14 is provided near the lower end, just above a side inlet 14 for water: a side outlet 14 is provided above the valve seat diametrically opposite the inlet opening. The valve, 15, has preferably a seat, 15, a three-foiled body part 15 and a round eX- tension 15 which passes up through a bushing 16. which, with the body or case forms a stufiing boX. Below the valve, a spiral spring, 17, pushes it upwardly against the seat. A plug nut 18 closes up the lower opening. Coupling nuts 19, 20 are used to connect inlet and outlet pipes, respectively, 21, 22, with the body. The valve just described, and the flushing valve with which it operates and which is described hereinafter are old and tried devices, and are made use of by me and described so as to show a complete working device, but other water'flushing devices, operated by a plunger to open a valve initially, may be employed in connection with the ring and diaphragm construction first described and which is the essen tial feature of the invention.

The flushing valve is comprised of a cylinder case body 23, having a side outlet 23 near the top, where a connection is provided with the pipe, 21, by means of a coupling nut 24. Below this side outlet and near the lower end of the body is a water inlet 23 which connects with the supply pipe 25 for flushing the urinal. A coupling nut 26 fastens the pipe to the body. Diametrically opposite the water inlet, and just below it, is an inlet 23 to which the pipe 22 is connected by a coupling nut 27. On a line with the water inlet 23 a valve seat 23* is produced upon which a floating valve, 28, rests. This valve is cup-shaped above the seat, the diameter being reduced below the cup and again below the seat, so that when the valve is raised from its seat by the pressure of the water coming through the inlet pipe, 25, the perforated tail piece, 28, will permit the free influx of the water. A small hole 28 is drilled in the cup to permit passage of a small quantity of water. The lower end 23 of the valve body is threaded for connecting with the spray, 30, of the urinal, a pipe, 31, connecting the two. The upper opening of the valve casing is also threaded for the reception of a cap nut 29 having a central stem 29 to limit the upward movement of the valve 28.

32 is a trap.

Such being the construction, the operation is as follows :-The ring, 2, pipe 4 and inner part of the diaphragm chamber 5 are completely filled with a fluid, either gaseous or liquid, which quickly expands or contracts under the influence of a varying temperature, ether or spirituous alcohol may be employed. When all the water connections are made and the urinal is not in use, water will be under pressure in pipe 25, valve body 23, pipe 21 to and under the valve 15 in body 14. The crank lever 11 is so adjusted that the screw 7 on the diaphragm 6 contacts with the inner end while the screw 13 is adjusted so as to rest on the valve stem 15 of the valve 15. lVhen the urinal is in use, the liquid passes over the ring, 2, the fluid contained therein immediately begins to expand and continues such expansion until the diaphragm 6 is pushed outwardly, the flushing mechanism is set in operation by the depression of the valve 15 which releases the water above the valve 28 causes it to raise from its seat and permit the influx of the flushing water through pipes 25 and 31, some of the water passing up through the hole 28 in the valve 28, and when the pressure above the valve 28 becomes greater than that of the water in pipe 25 (owing to the balancing of the pressure plus weight of valve) the water supply is, shut ofi', the colder Water causing the fluid in the ring 2 to contract and the diaphragm to recede. For varying out door temperatures the screw 13 is adjusted to suit conditions.
